In 1972 ALL Cutlass convertibles were Supremes. And since you're buying headers, tell the header company that it's an "S", because otherwise they'll tell you the headers won't fit a Supreme. That's an urban myth that many of us have been trying to kill for many years. All you need to know is that the frames are identical forward of the firewall, the engines are identical, the motor mounts are identical, there is no mythical engine offset, there is no mythical difference in the convertible... do you sense this has come up before?
